Arsenal midfielder Alex Oxlade-Chamberlain is understood to be mortified after 'liking' a tweet which called for Arsene Wenger to leave the Gunners.
The England international made the error scrolling through Twitter after Arsenal's 3-1 loss at Chelsea on Saturday.
He inadvertently pressed the heart-shaped 'like' button on a post by Arsenal Fan TV, which read "Wenger needs to go".
Oxlade-Chamberlain quickly realised his error and unliked the tweet, but some of his 2.2 million followers had already noticed and screen grabs were taken and posted.
Oxlade-Chamberlain later posted: "I didn't mean to like that post earlier obviously. Didn't even realise I had!"
